Problems solved by technology

However, the actual marked products have certain differences in the materials used. If the same laser parameters are used for marking, the marking effect will be poor in consistency.
[0004] In view of the above technical problems, the currently adopted method is to manually debug the marking effect and manually correct the laser marking parameters after discovering the difference in the marking effect, which leads to the occupation of manpower, and after the difference is found, defective products have been produced, which is wasteful. materials; and the downtime caused by debugging, the time and frequency of debugging have greatly reduced the equipment utilization rate

Embodiment 1

[0042] Such as figure 1 , figure 2 with image 3 As shown, a laser marking method is applied to a laser marking system. The system includes a laser marking component and a marking test component. The marking test component is used to test the laser marking component on the actual material. The grayscale relative value of the image.

[0043] The laser marking assembly used in the present invention includes a laser that emits laser light 60 and a vibrating mirror 1, wherein the vibrating mirror is used to generate a marking image, a beam expander for beam expansion and a field lens 2 for focusing the laser. The optical path direction of the laser 60 emitted by the engraving component is the horizontal direction.

[0044] Such as image 3As shown, the marking test component used in this example is a quasi-coaxial optical path detection component. The quasi-coaxial optical path detection component includes a reflective lens 4 and an image analyzer 3. The reflective lens 4 and...

Embodiment 2

[0069] Such as figure 1 with Figure 4 As shown, a laser marking system includes a control module, and a laser marking component and a marking test component respectively electrically connected to the control module. Among them, the laser marking component is used to output the laser marking image; the marking test component is used to test the relative gray value of the image to be checked marked by the laser marking component on the actual material; the control module is used to obtain the marking Test the relative gray value of the test component; judge whether the relative gray value matches the preset gray standard value; if not, call the corresponding laser marking parameters according to the relative gray value, and control the laser marking component Modify the laser marking program according to the laser marking parameters, and generate a marking control signal after modification; if so, generate a marking control signal; control the laser marking component to mark a...

Abstract

The invention discloses a laser marking method and system, and relates to the technical field of laser processing. The laser marking system comprises a laser marking assembly, a marking test assemblyand a control module; the laser marking assembly is used for emitting laser for marking images; the marking test assembly is used for detecting the gray relative value of a to-be-detected image markedin real time on an actual material by the laser marking assembly. According to the laser marking method and system, when laser marking is conducted, the gray relative value of the actual material isobtained by actually marking the actual material; and appropriate laser marking parameters are taken according to the gray relative value of the actual material, thus the laser marking assembly corrects a laser marking program according to the parameters and emits the appropriate laser to mark a product of the corresponding material, and the problem that the marking effect is inconsistent due to the actual material difference is solved. The laser marking method and system can ensure the consistency of the marking image effect, the production efficiency is improved, and the scrap rate is decreased.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a method and system for ensuring consistency of laser marking effects by identifying material differences in real time. Background technique [0002] Laser marking is a chemical reaction in which a high-energy-density laser beam is used to locally irradiate the workpiece to vaporize the surface material or undergo a color change, thereby forming a permanent mark. Laser marking is a technology in which the laser and the material interact to produce discoloration on the surface of the material. Different materials have different reaction characteristics when irradiated by laser light, resulting in different effects of different materials. [0003] Existing laser marking usually uses a laser as a laser generating device. The laser generated by it reaches the galvanometer after beam expansion and collimation, and then the laser beam is focused by a field mirror and projecte...
